TAKE-UP MECHANISM FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent No. 789,816, dated May 16,1905.

Application filed lIuly 25, 1904. Serial No. 217,903-

ment permitting a very large roll of cloth to be wound.

The take-up roll in the low-roll type of mechanism is located lower downin the loom, the cloth passing thereto from the fell in a differentmanner.

The several advantages attendant upon each type and also some of theobjections thereto are set forth at considerable length in United StatesPatent N 0.7 43,584, dated November 10, 1903, to which reference may behad, such patent disclosing a structure which may be changed readilyfrom the low-roll to the highroll type of take-up when desired.

A high-roll take-up mechanism is shown in United States Patent N 0.643,284, and in practice it has been found that in weaving certain lightgoods the sawing action of the cloth over the sharp points on thesurface of the high take-up roll is apt to cut the threads in the clothand damage the latter to a greater or less extent. It has been foundnecessary, therefore,when weaving such cloth to provide means whichwillprevent the sawing movement of the cloth,while preserving theadvantageous features of the high take-up roll.

The ordinary loom of commerce is provided with means which areinterposed between the fell and the take-up roll to prevent such sawingmovement of the cloth, but so located that the take-up roll must beplaced at some distance below the breast-beam, thereby very materiallyrestricting the size of the roll of cloth which can be Wound.

My present invention has for its object the construction of a novel formof high-roll takeup mechanism so arranged that by means of friction orsupporting members the sawing action of the cloth over the take-up rollis eliminated and not only is the desired length of cloth providedbetween the fell and the takeup roll, but several modifications in thepath of the cloth can be used, including the direct passage of the clothfrom the fell to the roll, when the cloth is of a character to make itdesirable. The take-up roll is also adjustable, so that the filling iscaused to be beaten in toward the top, center, or bottom of the wovencloth in order to impart the required surface or finish thereto.

The various novel features of my invention will be fully described inthe subjoined specification, and particularly pointed out in thefollowing claims.

Figure 1 is a partial front elevation of the take-up mechanism of a loomembodying my present invention. Fig. 2 is a transverse seetional detailthereof on the line 2 2, Fig. 1, looking toward the right. Fig. 3 is arear elevation of a portion of the take-up roll and some of the adjacentparts looking at Fig. 2 toward the right. Fig. 4 is an inner side viewof a portion of the train of gearing intermediate the take-up roll andthe actuatingattached to the breast-beam and which has' a bearing forthe journal of the take-up roll. Fig. 7 is a similar view of one end ofthe removable cloth-support and the connected part which is detachablysecured to the bracket shown in' Fig. 6. Fig. 8 is a cross-sectionaldetail taken on the line 8 8, Fig. 1, looking to the left, to show moreclearly the direction of travel of the cloth from the fell to the takeuproll and roll of cloth, the arrangement corresponding to thatillustrated in Figs. 1, 2, and 3. Fig. 9 is a similar section, butshowing the parts differently adjusted to provide a shorter length ofcloth between the fell and the take-up roll and also adjusted to changethe inclination of the cloth from the fell. Fig. 10 is a like viewshowing yet another adjustment of the parts with the take-up rolllowered and a dilferent inclination of the cloth; and Fig. 11 is asection on the line 8 8, Fig. 1', showing the parts adjusted for thedirect passage of the cloth from the fell to the take- I up roll, thelatter being shown in its highest position.

The loom side A, take-up pawl [4 pawl-carrier a, ratchet a", with whichthe pawl cooperates, the cloth roll or bar 0, having its journalsmounted in downwardly-movable supports Fig. 2, and the take-up or sandroll T, having a piniont on the take-up-roll shaft z/ and mounted abovethe cloth-roll G, are substantially in Patent No. 643,284, except thatherein the take-up roll is vertically adjustable, as will be described.

The gear tmeshes with a large gear t, Figs.

1, 4, and 5, having its hub rotatably mounted on a tubular boss t Fig.5, provided with an enlarged circular base 6 the boss being clampedrigidly to a plate M by a stud-bolt 25' and nut 6 the plate beingfastened to the loom side and having a segmental slot m Fig. .4, throughwhich the bolt passes.

Inasmuch as the take-up roll is vertically adjustable, as will beexplained hereinafter, it is necessary to raise or lower the gear t tomaintain it in mesh with gear 1; when the takeup roll is adjusted, andthis is provided for by the adjustability of the stud-bolt If in theslot m/ The enlarged base 6 passes easily through a hole in achange-gear-supporting member or plate N, so that the latter can beadjusted angularly, a clamping-bolt t passing through a segmental slot ain plate N and a vertical slot at in the offset part M of plate M, acollar t Fig. 1, through which the bolt-t extends. being interposedbetween part M and the plate N.

The change-gear t has an attached pinion t to mesh with the gear t, saidpinion in all cases having the same number of teeth, while the teeth ofthe change-gear varya construction well known to those skilled in theart.

A radial slot a (see dotted lines, Fig. 4)

receives a stud t on which the change-gear 2? is mounted, radialadjustment of the stud N about its fulcrum t in one direction or theother, while the distance between the centers of pinion 25 and gear 6 ismaintained substantially constant. The adjustment of'the latter gear toaccommodate vertical adjustment of the take-up roll carries with it thebodily-vertical adjustment of the change-gear-supporting member N, asthe stud-bolt 6 provides for both adjustments.

' The arrangement of the angularly-adjustable member N and thechange-gear sustained thereby is similar to that shown and described inUnited States Patent No. 730,404; but therein the take-up roll isnon-adjustable and the vertical adjustment of member N is unnecessary.

Referringto Figs. 1 and 2, the downturned ends of the breast-beamcasting A are provided with upright slots'l to receive headed bolts 2,provided at their outer ends with cla111ping-nuts 3, the bolts passingthrough horizontal notches 4in the part 5 of acasting, (shown separatelyin Fig. 6,) one of these castings being vertically adjustably mounted ateach end of the breast-beam. Each casting has a horizontal sleevebearing6, in which the adjacent journal 25 of the take-up roll is rotatablymounted, so that by adjusting the castings by means of the slots 1 andbolts 2 the vertical position of the take-up roll is changed. A verticalear 7, having a hole 8, projects rearwardly from each casting, andthe'inner end of the latter is upturned at 9 and provided with apreferably bevel-ended seat 10. (Clearly shown in Fig. 6.) Short arms 11are bolted to the ears 7 by means of clamping-bolts 12 passed throughthe hole 8, the arms having two bolt-holes, so that the position of thearms may be changed, as shown in Figs. 8 and 11, each arm having at itsrear end an upright seat 13 for the correspondingly-shaped lugs 14 of abar or red 15.

As shown in Figs. 2 and 8 to 11, inclusive, the bar or cloth-guide 15 islocated behind the take-up roll, and it may be adjusted to a positionabove or below the center thereof, as may be desirable or necessary, andwhen set such cloth-guide 15 willpartake of any change in the verticalposition of the take-up roll. A cloth-support is herein shown as anelongated metal bar 16, preferably a casting having a flattened upperface 17 and front face 18 with well-rounded corners, the cross-sectionalshape of the support or bar 16 being very clearly shown in Figs. 8 to10, inclusive, the longitudinal lower front and back edges 19 and 20being also rounded, as shown. The surface of this support or bar ispolished to present no irregularities or projections upon which thecloth might catch or tear, and at its ends it is formed with integralfeet 21, which extend rearwardly therefrom at right angles thereto. Asmost clearly shown in Fig. 7, each foot has a recess 22 to receive theseat 10, and the feet are detachably secured thereto byretaining-screws23, passing through holes 24 in the feet and screwedinto threaded holes 10 in the tops of the seats. The extremities of thefeet 21 have upright seats 25 formed therein in their inner faces toreceive the reduced ends 26 of a removable supplementary cloth-support,shown as a cylindrical bar or roll 27, which is supported behind themain support 16 and also above the take-up roll, as is the said mainsupport. The supplementary support may be and preferably is made ofmetal polished to present a smooth surface, over which the cloth passes.

In Figs. 2, 9 to 11, inclusive, the beatingup point or fell is indicatedat f. The ad justment of the parts in Figs. 2 and 9 is such that thecloth (1 passes from the fell forward over the flattened top and frontfaces 17 and 18 of the main support 16, thence under the same, crossingthe rounded edges 19 and 20, and up over and down behind thesupplementary support 27 and passes thence to the take-up roll T. Adouble or reversed loop is thus formed in the cloth between the fell andtake-up roll, so

that such a length of cloth is interposed as will absorb and dissipatethe back-and-forth or sawing movement of the cloth before it reaches thetake-up roll. The cloth thus rests quietly on the latter and is heldwith proper firmness to e'fli'ect the proper tension for taking up, butwithout any sawing or rubbing action over the surface of such roll.Passing around and under the roll the cloth is then carried over andaround the cloth-guide 15 and thence to the cloth-roll C, upon which itis wound in usual manner, a large portion of be properly adjusted, themain and supplementary cloth-support maintaining the same position withrelation to the roll.

Referring to Fig. 9, the roll and cloth-supports have been loweredsomewhat, and the cloth now passes from the fell over the supplementarysupport 27 and under the rear corner 20 of the main support to thetakeup roll, a shorter length of cloth being interposed between the rolland the fell. The inclination of the cloth from the fell forward isdifferent also; but it will be manifest that by raising the roll T andthe cloth-supports the inclination can be changed without varying thelength of cloth between the fell and the roll. In Fig. 10 the verticaladjustment of the parts is substantially the same; but the cloth leadsdirect from the fell to and over the main support and thence directly tothe take-up roll. A considerably smaller portion of the take-up roll isby this arrangement brought into engagement with the cloth, as will beclear from an inspect-ion of the drawings.

Should it be desired to lead the cloth direct to the roll from the fell,as will be the case in weaving some kinds of cloth, it is only necessaryfor the weaver to loosen the two bolts 23 and lift off bodily the mainand supplementary cloth-supports, as shown in Fig. l, and the take-uproll can be elevated to its maximum height or to a lower position, asmay be desired.

Changes in the position of the take-up roll require an adjustment of thegear 2? and the change-gear and its supporting member N; but suchchanges are easily and quickly made by means of the constructionheretofore described.

A great variety of changes in the lead of the cloth, the length thereofbetween fell and take-up roll, and inclination of the cloth forward ofthe fell can be secured by the construction herein shown and described.

My invention is not restricted to the precise construction andarrangement herein shown, as the same may be varied or rearranged invarious particulars by those skilled in the art without departing fromthe spirit and scope of my invention.
